Job Overview

The Materials Planner is responsible for ensuring material availability to support production requirements, spare parts orders, and planned inventory needs. This position will manage material planning activities with primary responsibility for Spares, Material Availability, and Stock Run Work Orders.

The Materials Planner will review customer and internal demand, inventory levels, open purchase orders, work orders, bills of material, and material shortages to ensure required components are available when needed. The position works closely with Planning, Purchasing, Inventory Control, Production, Customer Service, and other cross-functional teams to identify material risks, establish priorities, and support on-time delivery.

Success in this role will be measured by material readiness, timely execution of Spares orders and Stock Runs, shortage reduction, inventory visibility, work order execution, and effective communication of material risks.
